"But make no mistake," McCartney writes bluntly, "it's still an
airplane."

Based on the passengers McCartney surveyed, it seems that the
difference is not immediately noticeable, but cumulative. The
combined effect of the 787's new features might make you feel,
retrospectively, that you've had a better flight.

The 787 is supposed to offer U.S. service later this year,
McCartney writes, so you can find out for yourself soon enough if
you haven't already.
